Vivint Solar is a legacy brand
Vivint Solar was acquired by Sunrun in 2020, so new shoppers should confirm current solar offers, account support, and warranties with the active provider rather than relying on old Vivint Solar sales material.

Vivint Solar Reviews: What Happened to Vivint Solar and What Homeowners Should Know
Vivint Solar used to be one of the best-known names attached to residential solar leases and power purchase agreements. Today, the useful question is not whether to buy “Vivint Solar” as a new standalone product, but how to understand old contracts, Sunrun account migration, rooftop-solar economics, and the difference between solar equipment and Vivint smart-home security.
Solar is not the same as security
Vivint smart-home security and legacy Vivint Solar programs may appear together in old searches, but alarms, cameras, monitoring, panels, inverters, batteries, leases, and PPAs are separate decisions.
Contracts matter more than slogans
The most important details are equipment ownership, lease or PPA escalators, roof obligations, production guarantees, buyout terms, transfer rules, and what happens if you sell the home.
Battery backup changes the security story
Solar panels alone usually shut down during an outage unless the system has a properly configured battery or backup gateway. Security buyers should not assume rooftop solar keeps alarms and cameras online.
Archived page, refreshed: This legacy Vivint Solar URL has been refreshed because many older bookmarks and search results still point here. Vivint Solar is no longer a standalone home-security sister brand; it was acquired by Sunrun in 2020. Use this page as a practical explainer before comparing current solar, battery, and home-security offers.
What happened to Vivint Solar?
Vivint Solar began as a residential solar company associated with the broader Vivint ecosystem, then became a major public solar installer before being acquired by Sunrun in 2020. That history matters because many homeowners still search for Vivint Solar reviews when they are really trying to understand an older lease, service issue, roof question, production guarantee, or account transfer. If you are shopping today, verify the current provider, contract name, and support path before assuming old Vivint Solar terms still apply.
How to read old Vivint Solar reviews
Older reviews often reflect door-to-door sales expectations, installation scheduling, financing details, utility interconnection delays, roof condition, production estimates, and customer-service experiences from a different operating period. Treat them as useful context, not a current price sheet. The review that matters most is the written contract in front of you: lease, PPA, loan, cash purchase, battery add-on, maintenance terms, warranty exclusions, and cancellation rights.
Lease, PPA, loan, or owned system?
A solar lease or power purchase agreement can reduce upfront cost, but it also adds long-term obligations and transfer questions. A loan or cash purchase may offer more ownership control but leaves the homeowner responsible for comparing equipment, installer quality, warranty service, and incentive assumptions. Before signing any solar agreement, model the total cost over the full term and compare it with realistic utility-rate assumptions, not only the first monthly payment.
What legacy customers should verify
If your home already has a Vivint Solar-branded system, gather the agreement, account number, installer documents, inverter and panel model numbers, monitoring login, utility interconnection approval, production guarantee, roof-penetration warranty, and any transfer paperwork. Confirm who currently services the account, how to request repairs, how production is measured, and what documents a buyer will need if you sell the property.
Solar, batteries, and home security backup power
Solar panels do not automatically power a home-security system during an outage. Most grid-tied systems shut down for line-worker safety unless paired with a battery, backup inverter, and correctly wired critical-loads panel. If alarm uptime is part of your reason for considering solar, ask specifically whether the modem, router, alarm hub, cameras, smart locks, garage opener, and any medical or life-safety devices are included in the backed-up circuits.
Questions to ask before signing a current solar quote
Ask who owns the equipment, who services it, what happens if the roof needs repair, whether the price escalates, how production is guaranteed, how incentives are applied, what cancellation rights exist, how the agreement transfers during a home sale, and whether battery backup is included or merely shown as an optional add-on. If the salesperson cannot answer in writing, slow down.
When to compare Vivint security separately
Home security should be evaluated on its own merits: sensor coverage, camera placement, monitoring price, contract terms, app reliability, backup power, and privacy controls. A solar proposal may be valuable, but it should not distract from comparing alarm equipment and monitoring as a separate safety purchase.
Vivint Solar legacy account checklist
- Confirm whether you are dealing with a legacy Vivint Solar account, Sunrun support, or a current third-party solar quote.
- Read the full lease, PPA, loan, or purchase agreement before comparing monthly savings claims.
- Check escalators, buyout terms, production guarantees, transfer rules, and roof-repair obligations.
- Verify who owns the panels, inverter, monitoring hardware, and any battery equipment.
- Ask how outage backup works and which security, network, or life-safety devices are actually powered.
- Keep solar financing separate from home-security monitoring decisions.
- Save account, warranty, permit, utility, and interconnection documents for future service or home-sale questions.
Vivint Solar FAQ
Is Vivint Solar still in business?
Vivint Solar is no longer a standalone public solar company. It was acquired by Sunrun in 2020, so current support or new solar offers should be verified with the active account holder or provider.
Is Vivint Solar the same as Vivint home security?
No. The names are related historically, but rooftop solar agreements and Vivint home-security systems involve different equipment, contracts, billing, warranties, and support questions.
Do Vivint Solar panels power my security system during an outage?
Not by default. A typical grid-tied solar system shuts down during an outage unless it includes properly configured battery backup and backed-up circuits for the alarm hub, router, cameras, or other devices.
What should I do before buying a house with legacy Vivint Solar?
Request the full agreement, transfer terms, payment history, production reports, roof warranty details, equipment list, and current service contact before closing. Have the contract reviewed if the obligations are unclear.
